iuted 51am HENRY A. GAGE, OFv MANCHESTER, NEW HAMPSHIRE.

A Lerma Patent No. 96,791, dated November 16, 1869.

IMPROVEMENT IN MACHINES POR CUTTING PASTEBOARD.

The Schedule referred to in these Letters Patent and making part of thesame.

' being had to the annexed drawings, making a part of thisspecification, in which- Figure 1 is a longitudinal elevation. Figure 2,a perspective view. Figure 3, a transverse section. Y v Figure 4, aportion of lever 2e and cam g.

Fig. 1 shows the moving knife a, the movable gauge c, and slide d, forremoving the card, in combination Awith the lever e the inclined tableb, on which the card-board is placed previous to cutting, and the racks1', with the guides m, for moving and setting the gauge c,- also thelevel' l, by which the knife ais operated.

Fig. 2 shows themovable knife 'a and stationary knife y, t-hey leversl'l, and. cranks 1 and 2, and the shafts; also, the hand-wheel k, formoving the pinion j, and, by the racks fi, setting the gauge c; also,the cam Gr and the rod f, attached to the lever e, by which the slide dis worked to clear oi` the cards after cntting.

Fig. 3 shows the rack t' and pinion j, the guides m,

The machine is worked by means of the cranks v1 and=2, and the cam gattached to the shaft S.

Y The cranks are .attached to the knife a by the levers I, and one beinglonger than the other, throw that end of the knife further than theother, s'o that when this movable knife is brought back, and comes incontact with the card-board, which has been placed on the inclined tableb, and fallen down upon the gauge c, and against the stationary knife y,the board is cut at one end of the knife a, between it and the knife y',before the other is reached; '71. e., a shear-cut is produced. The sameresult would be produced if 'the levers l were of different lengths, andthe cranks of equal lengths.

The card being out, rests on the gauge c, when the movement of the slide.d throws it otf.

What I claim, and desire to secure by Letters Patent, is

l. The movable knife a., when adj usted and operated by levers or cranksof different lengths, or their equivalents, from main shaft, so as toproduce a shearcut, substantially as describcd'and for the purpose setforth. i

2. The combination of the lever e, theslide d, the cam g, and the rodj', with spring for clearing the card after it is cut.
